I’d contact the teacher and ask for the course content on “helping to save the planet” and specifically say you do not want your child force fed global warming nonsense. At least it gives the teacher a heads up that you’re keeping an eye on them and you can review whether the material is propaganda at the same time.
This is good advice. You might also suggest that she view "The Great Global Warming Swindle":

By the way, other than that, a Catholic education is an excellent education!
